Why, it's almost like you should have programmers program during an interview. A previous company I worked for did that. Build a small ad-hoc team of 3-4 people (with 1-2 existing employees, as knowledge repositories), and let the candidates work on a sort-of real problem for pretty much a day. Every team member occasionally came in and watched for a while, every team member looked at the repo for the end results, and the "embedded" people gave feedback on how it felt to work with the candidates. Yes, it's expensive. But so is a mishire, and it sure did work well to filter people out.
